I will report here with feedback on the closed deck block since this thread seems to be the hub for info on it. I don't want to clutter the thread, but my time attack car makes a good amount of power (for a 4 cylinder Subaru) and we'll see if I have any cooling related issues with the closed deck block. I ran the whole 2013 time attack season on one longblock without touching it so we know I had no issues with stock block halves. I'll test the new block in the power range I ran last year for a bit, then turn the boost up once I've given it a thorough run at the same power for comparison.

Same here, never had an issue with stock cases, cooling, or head gaskets so maybe I am not the best person to try and break this thing lol. So far I have just broken rods in the process. BTW thanks Mike for the backup goodies

That just means when something breaks it won't be because you're a bonehead...which is exactly what you want from a test.

And you're welcome for the goodies. You legitimately got them for half of distributor cost, but I'm in clearance mode and I'm glad they went to a good home.

Have you figured out a procedure for the film test? Or figured out what you're looking for exactly?

Improvements over stock. Better distribution of forces and higher clamping forces would be ideal, but I think that may be too much to ask for by merely changing studs. I hope I'm wrong. The biggest problem is that how they come from the factory cannot be duplicated

Shes just about ready to race. Swapped out dampers yesterday, put new plugs in, and took a quick spin with the new chassis setup. Boy does it feel good . All I have left is purely aesthetic. Don't feel like putting my headunit back in so I am going to slap a piece of aluminum in there and mount my MAPDCCD there for now. Going to hold off on installing the window net and master cutoff until I actually make some fast passes. Once that happens I will get the stuff installed and go for my NHRA license.

The holes in the EJ22T block line up with the head gaskets to allow for sufficient coolant flow.

Many of the holes in the Outfront deck plate and head gasket do not line up. I'm not happy about it and I'm debating going another route.

the holes in the EJ22T block do not line up with the current AVCS heads well, and cause cooling issues. people associate this issue with closed deck in general, when they hear closed deck they automatically assume overheating.

the outfront block has not shown to have any issues, it HAS been run in road racing and time attack applications in the subaru platform with no ill effects.

dumping a motor and going a different route based on nothing more than an educated guess is a little over the top.

I would be more than willing to bet that outfront has collected feedback from their customers on the cooling performance of the closed deck motors. they are on the 3rd version, if there was cooling issues don't you think they would have addressed it?

If you ask, they will be happy to share with you many improvements that have been made, one thing that was under heavy research was the cooling performance, that is a big player in the chosen thickness of the closed deck reinforcement.

Mike outfront posted your answer! What issues did you have thermostat not opening? Airbound system?
